Artificial silk making apparatus



Aug. 18,1931. w. H. FURNESS ARTIFICIAL SILK MAKING APPARATUS Filed Jan.11, 1929 BY w 5 ATTORNEYS 7V $4 NVENTOR Patented Aug. 18, 1931 WILLIAMH. FURNESS, OF NATIONAL, PARK, NEW JERSEY, ASSIGNOR T FURHESSCORFORATION, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF NEW JERSEYARTIFICIAL SILK MAKING APPARATUS Application filed January 11, 1929.Serial No. 331,?79.

This invention relates to apparatus for making artificial silk.

In general the present invention consists in an improvement upon thearrangement of a my copending application, Serial No. 239,402 filedDecember 12, 1927, wherein I provide a battery of spindles for formingthe thread,

each spindle consisting in the main of a pump,

a spiimeret, a precipitating bath, cap twister mechanism and drawingmechanism for taking the formed precipitated thread and leading it tothe cap twister mechanism.

Heretofore I have provided each spindle with an enclosing casingprovided with doors giving access to the spindle, the casings beingconnected to a suction line for withdrawing the fumes.

This arrangement, while quite satisfactory in some respects, is open tothe objection that the doors must be opened to ascertain whether or notthe spinneret is spinning and the cap twister mechanism is laying thethread upon the spool or other device upon which it is to be laid.Operators must, therefore, be continually looking over the batteries.

The object of the present invention is to make it very easy to determinewhether any spindles are not making thread. More specifically it is anobject of the invention to make it possible to determine at a glancefrom one point whether any of the spindles of the battery are notfunctioning properly, while, at the same time, the fumes are withdrawnfrom the room.

I accomplish the foregoing, together with such other objects as mayappear hereinafter, or are incident to my invention, by means of theconstruction which I have illustrated in the preferred form in theaccompanying drawings, wherein Fig. 1 is a diagrammatic side elevationof a number of spindles of a battery of spindles, and

Fig. 2 is an end elevation of one spindle partially in section.

Referring now to Fig. 1, the reference character A indicates a batteryof spindles. With the exception of the drawing wheel 7 whichspecifically constitutes the subject matter of 5 my copendingapplication Serial No. 331,781

filed January 11, 1929, all of the parts of the spindle are notindicated. For the pur oses of the present invention it sufiices toil1ustrate the drawing wheels.

Around each spindle is a casing 8 provided with a slot 9 in its upperpart. The drawing wheels 7 extend above the slot so as to be exposed toView. The fumes are drawn from each spindle through the pipes 10, ofwhich there is one connected to each spindle, and to a main suction line11. As the fumes are withdrawn from each casing, room or otheratmosphere is drawn in through the slot.

Thus, an operator at a glance can determine whether any spindle is notfunctioning properly. For example, if a spindle is not making thread,there will be no thread on the drawing wheel. If the spindle is makingthread, but the thread is not being laid upon the spool, it willaccumulate upon the drawing wheel. The operator can thus determine,without moving from a given spot, whether the spindles are functioningproperly, while, at the same time, the fumes are withdrawn and noobjectionable quantity escapes to the room. The only occasion theoperator has to open the door 12 is to remove spools which have becomefilled, or to restart a spindle which is not functioning properly.

I claim 1. In combination, a battery of artificial silk thread formingspindles, each including a drawing wheel as a part thereof, a casingenclosing each spindle and having a slot in its top above which thedrawing wheel extends for exposure to view, and means for drawing ofl'fumes from the casings and for drawing room atmosphere into the casingsthrough said slots.

2. In combination, an artificial silk thread forming spindle including adrawing wheel, a casing around the spindle having a slot in its topabove which the drawing wheel extends for exposure to view, and meansfor drawing ofi' fumes from the casing and for drawing room atmosphereinto the casing through said slot.

In testimony whereof I have hereunto signed my name.

WILLIAM H. FURNESS.
